2. electrokid

all three angles of the two triangles are identical. -> by angle-angle-angle test, they are similar similar triangles maintain a constant side-to-side ratio

@electrokid so is it SSS?

4. electrokid

no -AAA

5. electrokid

6. UmmmHELP

yeah im sorry i still dont get it... i am not to good at this section my options are 10 1/2 and 4 2/3...how do I get it from there? im still confused

9. electrokid

if triangles are similar, their sides are in equal ratios

10. electrokid

so, ${x\over8}={7\over12}$
